Both Emperor Guillotine and the rest of the villains and the supporting cast were not Mitsuteru Yokoyama's creations and so they could not be used in the later seven-episode anime TV miniseries "Jaianto Robo: The Animation - Chikyuu ga Seishi Suru Hi."
Former Guns n' Roses guitarist Buckethead, a big fan of the TV series, has made several references to it within his music career. This includes naming his 1994 album and early band "Giant Robot" after the titular character. He often plays a rendition of the TV series' theme song during his live shows and also uses stock footage from the TV series in the background of some of his live shows on a large screen behind him if the venue he is performing at is capable of doing so.
